In the system design, we will use some feedback signals to protect system or calculate
watt. The protect signal include over current, over voltage, surge voltage and kettle detect.
Anyone of them appears, the system must stop work. If the IGBT temperature is raise over
60℃, the fan must turn on. If the IGBT temperature is raise over 120℃, the system must stop
work. If the kettle is empty, the plate temp will raise. If the temp raise up to 300℃, the system
must stop work.
